English term or phrase: dark current
Definition from Tyco Electronics Corporation:
The thermally induced current that exists in a photodiode in the absence of incident optical power.

Example sentence(s):
  • This voltage may be as low as 10 mV or as high as 50 V and the dark currents may vary from pA to μA depending upon the junction area and the process used. Dark current is always specified at a particular value of reverse applied voltage. optoelectronics.perkinelmer.com
  • The photodiode noise in is the sum of the thermal noise (or Johnson noise) ij of a resistor which approximates the shunt resistance and the shot noise isD and isL resulting from the dark current and the photocurrent. Hamamatsu Corporation
  • Dark current is dependent on temperature. While dark current may initially be low, it will increase as the device temperature increases. tpub.com

ρεύμα σκότους


Definition from own experience or research:
Το θερμικό ρεύμα που διαρρέει μια φωτοδίοδο απουσία φωτός, ονομάζεται "ρεύμα σκότους". Συχνά χρησιμοποιείται ο γενικότερος όρος "υπόστρωμα".

Example sentence(s):
  • Στην ανάστροφη πόλωση της διόδου και όταν υπάρχει απόλυτο σκοτάδι κυκλοφορεί ένα πολύ μικρό ρεύμα μέσα από την δίοδο το οποίο ονομάζεται ρεύμα σκότους. Το ρεύμα αυτό είναι της τάξεως των μΑ και όσο αυξάνεται η ένταση του φωτός στην δίοδο, έχουμε γραμμική αύξηση του ρεύματος, η οποία εξαρτάται από το μήκος κύματος του φωτός καθώς και από την ένταση της φωτεινής ροής πάνω στην δίοδο. - Ραδιοερασιτεχνική λέ�
